Hello!
I have a very strange issue with my accord (VII gen, 2.2 ctdi). The alternator was replaced in August but recently the battery dashboard icon has been coming on and off. I replaced the battery as it was quite old but that didn't make a difference.
What is strange is when the light comes on. For example, today in the morning I started the car and started driving. The battery icon came on shortly and was on for most of the journey (about 10 miles). It only went off when I stopped at traffic lights. I used the torque app connected to the obd port to check the voltage - it was always between 11.6 and 11.9 regardless if I had the ac or lights switched on or not or if the battery light was off.
Then I switched the engine off and after about 10 seconds turned it on again. The icon never came on and torque was reporting the voltage of a round 14v for the whole journey. Again, lights or ac on/off didn't make any difference.
It now seems to happen all the time - start car in the morning - problems with charging, restart the engine - charging is correct.
There are no fault codes.
I checked all the alternator and battery connections and earthing and they look fine.
Any idea what might be causing this?
Thanks!
